BOBSLEIGH.

Application filed July 14,

This invention relates to improvements in bob sleighs and the objects of the invention are to provide a durable and efficient sleigh of this character that can be readily taken apart to be stored away and which when in use is particularly adapted to carry heavy loads and to more satisfactorily accomplish the various functions required.

A further essential object of my invention is to provide a bob sleigh that can be of simple construction and that can be economically manufactured and kept in repair.

With the foregoing and other objects, hereinafter more fully described, the invention consists essentially in the novel ar rangement and construction of parts described in the present specification and illustrated by the accompanying drawings forming part of the same.

Referring now to the drawings in which like characters of reference indicate corre sponding parts in each figure,

Figure 1 is a plan view of my improved Sleigh.

Figure 2 is a side elevation.

Figure 3 is a rear end view.

Figure f is an enlarged section taken on the line 1-4l of Figure 1.

Figure 5 is a section taken on the line 5-5 of Figure. 4.

Figure 6 is a plan view of the holding plate.

Figure 7 is an enlarged section on line 7-7 of Figure 1. 2

Figure 8 is an enlarged section on line 88 of Figure 1.

Referring now more particularly to the drawings, 10 and 11 designate the runners, 12 the bench and 13 the bolster or swivel swingingly mounted thereon. The ends of the runners 10 and 11 are provided with plates 14 and 15 fixedly secured thereon and connected by bolts 16 with the shoes 17 of the sleigh. The ends of these plates are turned up and over andwelded so as to form a solid eye 19 adapted to receive a pin 20, while 21 is a draw or tongue bar adapted to fit between the runners and preferably bellshaped at each end, provided with shoeing rings 22, similar to the box of a wagon hub and into which the draught-bolt or pin is adapted to fit so as to allow a certain amount of play, sufficient for the working of the bench up and down and sideways and of the runners backwards and forwards. The draught-bolts or pins 20 are formed 1924. Serial No. 726,043.

with apertures 23 registering with apertures in the tongue bar to receive locking pins 24.- therethrough.

Referring now more particularly to the essential feature of my invention, namely the mounting of the bench and as illustrated in Figures 3 and 4C. This is operatively supported on the runners 10 and 11, the construction comprising plates 25 and 26 fixedly secured on the top of the runners 10 and 11- upon which are mounted upright locking pins 27 formed with a T-shaped top 28, adapted to lit into an oblong aperture 29 in the plate 30 on the underside of the bench so as to hold the bench down after the T- shaped locking pin has been given a half turn somewhat similar to a bolt and socket; joint.

On the plate 30 is secured a metal bearing 31 bent in the shape of a bracket with an oblong opening 32 therein registering with the aperture 29 in the metal end of "he bench. This opening 32 engages with the locking pin allowing play for it to provide for the motion of the runners up and down. It should also be noted that the bearing bar of the bracket 31 is slightly rounded so as to centre the bearing close to the said pin, and allow the runner to lift.

33 are U-shaped hook members formed with a lip on their inner ends adapted to engage with links 34 connecting the hooks to central pins 35 in each end of the bolster or swivel top of the bench so as to allow the hooks 33 to swing around their end of the bolster and form a bearing for a skid for loading purposes also preventing the bolster from working while loading.

The hooks 33 can also be used for connecting a chain to bind a load on the sleigh. The bolster is swingingly mounted on the bench by means of a central pin extending therethrough and into an opening in the bench, the pin being formed with an eye at its lower end to receive a locking pin and the bolster and bench being provided, respectively, with plates 36 and 37 forming a bearing for the bolster to swing on the bench.

From the foregoing it will be noted that the strain in drawing the sleigh comes entirely on the draught-bolts and that should one of these become damaged or broken they can be very easily replaced. These bolts hold the sleigh together and if made of sound material are not likely ever to break.

It may also be noted that the runners 10 and 11 are. constructed almost straight so that there is no cross-grain to the Wood and that the draught-eye is on the top or highest part of the end of the runner, thus preventing the end of the runner dipping down and getting caught in a hole or hollow.

The further result of constructing the runners as straight as possible is that it is notlikely to break nor are the other portions of the construction, particularly the benches and brackets.

The simplicity of the construction, while accomplishing the objects sought for, enables the sleigh to be easily taken apart and provides for the standardization of each separate piece.

The cross pole may be used with the pillar by placing both hooks on the same 'side of the pillar so as to raise the pole there on, lengthening the pillar and widening the load to any desired width.

As many changes could be made in the above construction and many apparently widely diii erent embodiments of my invention, within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

1. In a bob sleigh and in combination. runners, a bench having openings therein.

supporting members secured to the bench and provided with openings therethrough registering with the bench openings, a T- shaped locking pin rigidly carried on the runners and adapted to extend through the supporting members to engage and disengage with the bench opening.

2. In a bob sleigh and in combination, runners, a bench member having recesses therein provided with apertured plates, supporting brackets, having openings therein, rigidly secured to the bench, and a pin formed with an engaging head, turnably mounted on the runners and designed to loosely engage with the plate covered recesses in the bench whereby the bench is locked or unlocked on the runners.

In a device of the character described, the combination with the runners having pin carrying plates thereon, of a bench with an enlarged opening therein with a plate for said opening provided with a restricted aperture to communicate with the bench opening, a suppor'ing bracket on said plate, an. o 'icning in the bracket registering with the plate opening, the bracket and plate op rings being designed to receive the pin when half turned and the bench opening being designed to engage in a locking position with the top of said pin.

In witness whereof I have hereunto set my hand.

JOSEPH ARTHUR MILLER.
